VISA Driver Development Wizard

[mal11]

I found a reference to this great document called
Using the VISA Driver Development Wizard and NI-VISA to
Register-Level Program a PXI/PCI Device under Windows.

As I described in another post, I am having performance problems
using AccessHW to talk to a legacy ISA board under XP compared to
Win2k where performance was decent.
To rule out AccessHW as the problem and confirm that it is an
XP/hardware issue, I'd like to try another method of
reading memory at address 0xE0000-0xEFFFF.
Since the legacy ISA bus on my motherboard is actually
bridged from the PCI bus, is there anyway to hack with the
VISA Driver Development Wizard to do memory reads
on the ISA bus?
Perhaps making a fictious PCI card with a VISA driver?
any thoughts?
